I will be setting up a website hosted on GoDaddy in the near future. However, one of the key components to making this website work is it's reliance on text messages coming from my phone. I will use SMS messaging to text my server with specific updates (example: "on route," "no longer delivering," etc). The idea is I text a specific address and the server updates a text file with the specific information from the text message from my phone. Then, when someone goes to the website, it will pull data from the text file to determine the current status and act from there.
How would I set up such a service through a web hosting server? I am familiar with HTML, PHP, and JavaScript, but won't mind learning another language if necessary.
